N. Y., a corporation of New York Application October 7,1943, swasmosm I3 Claims. (Cl. 292-256) This invention refers to improvements inclosures for mechanical lubricators particularly the kindlwhich are usedon railway locomotives where they are located in positions subjected toa great amount of vibration.

Itv is one of the principal objects of the invention. to provide aquickly detachablemeans for I securely holding a hinged type oflubricator cover against its seat.

Another object; is to provide means whereby a clamping arrangementlocated outside the lubricator cover serves to exert pressure on thecover at a point between the supporting seating edges so as to preventthe cover from being tilted on its seat when the clamping means aretightened;

A further object is to provide clamping means thatrequire little spacewhen disengaged as Well as when inplace holding the cover closed.

Stil1= further objects will become apparent in thefollowingspecification and the accompany-- ing drawings in which I Fig. 1 is across-sectional view of a fragmentary part of alubricator body and itscover as heretofore in use shown in a closed position and with itsclamping member in dotted lines in an open poistion? Fig. 2 is across-sectional view of a fragmentary portion of a lubricator body andits cover embodying a. preferred form of the principles of theinvention, the cover being shown in a closed position; I

Fig. 3 is a fragmentary cross-sectional view similar to Fig. 2 showingthe cover clamping means in an open position;

Fig. 4 is a plan view of the lubricator body,

shown fragmentarily in Fig. 2, and its cover, with two cover clampingmeans and a sealing bar holding them in place;

Fig. 5 illustrates a modified form of ing member in a closed position;and

Fig. 6 shows the same member in an open position.

Like numbers of reference denote similar parts a clampthroughout theseveral views and the following specification.

In Fig. 1 which illustrates a former method for keeping a lubricatorcover closed, I0 is a lubricator body of a construction well-known inthe art having a cover II provided with a hinge bolt V I2. The cover His fulcrumed on the hinge bolt I2, and in its closed position makes atight joint against a seat [3. The. cover is provided with two lugs l4projecting from its side, each of which has a reduced rectangularterminal l5 over which a clamping yoke Hi is slipped, pivotally'securedto apin 11' in lug H! on. the body proper. The

clamping yoke has a screw l9 which serves to. hold the cover against itsseat. 'A sealing bar 20. is passed through the two terminals l5 and isheld in place by a suitableseal to prevent unauage of oil throughthatside of the lubricator cover farthest removed from the clamping lugs.

Now referring to the Figs. 2, 3 and l which embody the particularprinciples. of the invention,

2| is a topportioniof allubricator body which has a raised-seat 22foracover 23engaging this seat.

I 7 Cover 23 is hinged to'the lubricatorrbody with lugs 24 adapted tofulcrum about a pin 25 journalled within lugsl26; In the center of thecover a cap 21 is providedfor to permitfilling the lubricator with-oilwithout opening the main cover 23 which is opened only at times when itisv desired to make adjustments to the interior mechanism of thelubricator.

The cover locking means consists of a clamping member 28 having arms 29and 30 angularly disposed with respect to each other. A slot 3| isprovided for within the center of the junction of the arms .29 and 30 toaccommodate a link 32 adapted to fulcrum around a pin 33 transverselythrough the center part of the clamping member 28. Link 32 is pivotallysecured to a pin 34 fixed between two lugs 35 on the body proper.

The lower arm 30 of the clamping member 28' rests upon the body of thelubricator, while the upper arm 29 is provided at its end with a screw36 adapted to be screwed downwardly to press the cover 23 against seat22. 31 is a sealing bar passed through registering openings in thecenter part of clamping member 28 and link 32. This sealing bar isprovided with a suitable seal 38 of commercial"chara'cterandsuflifiientls ldose not to prevent 'tightclosin'gwf the cover."

When it is desired to lift the cover to an open position, the screw 36is loosened, the seal 38 broken and the sealing bar 31 removed! Th'i'spermits moving the clamping member 28 away and clear of the lubricatorcover 23'1".as sh6-wnlin Fig. 3, and the cover may then be raised bymeans of hand lugs 39 at the side of the cover shown inFig. 4.Inspection of the urawmgsmi-scmsew that in either the closed or openpositions the g 20 and a removable sealing bar through said linkclamping arrangement does not project objectionablyisbeyond th :contoursof-Hthel lubricator itself."-
